Communication Systems

Q1:

Noise can be reduced by increasing sampling rate

A true

B false

C can't say

D insufficient data

ANS:B - false

It is well understood that by increasing the sampling rate we can overcome to the aliasing effect, but the increase in the sampling rate means an increase in sampling frequency so somehow we are allowing noise frequencies to come in that increased frequency range.

Can anyone clarify me over this confusion?
